I tried a lot of fragment transaction ways but my default fragment is not launching while opening navigationdrawer activity.
public class MainActivity extends AppCompatActivity{
private DrawerLayout drawerLayout;
private NavigationView navigationView;
private int mSelectedId;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar)findViewById(R.id.tool_bar);
toolbar.setNavigationIcon(R.drawable.nav_icon);
setSupportActionBar(toolbar);
drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
navigationView = (NavigationView)findViewById(R.id.nvView);
setupDrawerContent(navigationView);
mSelectedId = R.id.home;
selectDrawerItem(mSelectedId);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
selectDrawerItem(menuItem.getItemId());
return true;
}
});
}
// @Override
// public boolean onCreateOptionsMenu(Menu menu) {
// // Inflate the menu; this adds items to the action bar if it is present.
// getMenuInflater().inflate(R.menu.menu_main, menu);
// return true;
// }
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
switch (item.getItemId()) {
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
}
public void selectDrawerItem(int mSelectedId) {
// Create a new fragment and specify the planet to show based on
// position
Fragment fragment = null;
Class fragmentClass;
switch(mSelectedId) {
case R.id.home:
fragmentClass = Main.class;
break;
case R.id.orderhistory:
fragmentClass = Order_history.class;
break;
case R.id.profile:
fragmentClass = Profile.class;
break;
case R.id.contact:
fragmentClass = Contact.class;
break;
case R.id.polices:
fragmentClass = polices.class;
break;
default:
fragmentClass = Main.class;
}
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
// Insert the fragment by replacing any existing fragment
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.flContent, fragment);
fragmentTransaction.commit();
// Highlight the selected item, update the title, and close the drawer
// menuItem.setChecked(true);
// setTitle(menuItem.getTitle());
drawerLayout.closeDrawers();
}
}
Its still showing the activity first while launching. do pass suggestions so as i can move forward.
